# Schema / Taxonomy

## Introduction

When you build a connector using the [connector builder](/product-documentation/developer-hub/connector-builder.md), available [field mappings](/product-documentation/process-flows/building-process-flows/process-flow-shapes/standard-shapes/map-shape.md) are determined by the [data schema](/product-documentation/developer-hub/connector-builder/building-your-own-connector/4-endpoints/endpoint-options/schema-taxonomy.md) specified for the endpoint. The `schema / taxonomy` tab is divided into two panels - for example:

<div align="left"><figure><img src="/files/CqnSgbZbqzlS0xr887Sj" alt=""><figcaption></figcaption></figure></div>
